Imagine being able to live in 4D for a few minutes, then being cast back to the 3D world, feeling enlightened but permanently trapped.
We all exist in the fourth dimension, we are only not capable of perceiving it. If one were to be able to perceive the fourth dimension, it would be of no use, but once given the ability to freely manipulate the fourth dimension, you're stepping into psychic territory. Which really wouldn't even require the perception of the fourth dimension, merely the understanding of how it affects the third dimension that we're capable of perceiving. At least, I don't think it'd be of any use otherwise.
True. If the theory is right anyway, we're all 3D cross-sections in greater dimensional worlds. Weird to think that.
Technically we exist in all dimensions that also exist, but are bereft of the ability to perceive them, at least not as objects of their actual dimensions. For example a 4D object would appear as 3D cross sections before seemingly disappearing from existence

we'd probably either be ripped apart by supergravity, die from whatever oxygen or gravity was there, or be put back inverted with our insides outside our body because a higher dimensional being can do that, let me explain, imagine us pulling out a flatlander from their dimension and flipping them over to put them back, imagine that on a higher dimensional scale
Watching this as a 4d person must be rly funny
we are watching this in 2d, as screens are 2d
4d people wouldn’t be watching it, they’d be tasting it or some sht 😂
It's like seeing a projection of a 3d cube move on a 2d plane. We're basically seeing what a 4d creature would see but we don't intrinsically perceive depth in the 4th euclidean dimension, which is why the figure seems distorted to us but to a 4d creature that has access to a dimension perpendicular to ours, they can just move into that perpendicular direction and see that the "shorter" sides are in fact not short and are of equal length as all the other sides, while we would have to move the 4 dimensional object for it to project into the 3rd dimension because we're only allowed to move in 3 dimensions.
@@spectralanalysis u smart bruh i think understanding the 9 dimensions in space and 2 dimmensions in time are important to proving and understanding string theory and why gravity exsists at a sub atamoic level but its funny because these dimensions only exsist when you get smaller than sub atomic so seeing people make this stuff is cool but slighty funny i think

Thankyou for the visualisation of 4D as time. Its something I've been thinking about on a personal philosophical level. It brings me a lot of comfort thinking about myself as part of this huge 4D object. Knowing that as time passes; the things and people I remember and love and miss continue to exist as part of a 4D space. Like - they're not gone, gone, I'm just past the point of perceiving where we overlapped.
That's an interesting way of thinking! Loved it!

Maybe mixing the two softwares of the trail and the 4D space
Sounds interesting and cool but impossible.
something that is similar to this is the game miegakure, this video here ua-cam.com/video/vZp0ETdD37E/v-deo.html (by the creator of the game i believe) explains how 4d objects that have known objects, such as crystals, as their 3d shadows are built (though the shadows of course aren't always completely the object but partially the object but you get the gist)
I wonder, could we place a ball in a sub cube of the hypercube, and then rotate the hypercube through 4d space much like you would rotate a cube on the 3rd axis to reorient the painted side of a cube, if we placed a 3d ball in one of the 3d sub cube shadows of the hypercube, and all sides of the hypercube were solid in 3d space terms, would the 3d ball be crushed as the sub cube shadow warped out of our plane kf perception and existance, or would it, much like a painted side of a die, seemingly warp through space as it moved into an axis that we are unable to perceive, and then reappear in a different part of 3d space as the cube reorients in 4d space? If it is the latter, technically we woulld have invented pocket dimensions by our terms, or a bag of holding for instance. As the cubbe moves out of 3d space and into 4d space, i imagone the cube seemingly blinks out of existance for us, but my other idea, of harnessing this, would essentislly be akin to a glove to some deevice, that much like if a 2 dimensional creature pushed into space itself in it's context, would reach into 3d space, could we do the same with 4d space, and essentially create warping technology of sorts, or other aplications that would almost appear like magic or super powers
What makes me sad is that the fact, scientist like Carl Sagan can't see this beauty anymore, despite they only left us several years too soon 😓😓😓

lol good one
+GameGirl872 *Sciencephile the AI*
That is not a 4 dimensional object. 4D is impossible. You cant even conceive of it.
Again, this is NOT the 4d object, is the 3d shadow of the 4d object...
this is as much a 4D object as objects in "normal" games are 3D. The fact that you display it on a 2D surface doesn't make it any less three dimensional.
What you are neglecting is that the only reason a 2d object can be observed as 3d on a 2d medium is because we know what are the implications of observing in 3d and what images and objects do on this medium. We dont have the information to make ourselves model that behavior onto 3d objects that represent 4d objects. In 2d we know where the shadows and the distance in relation to point of view relate to our 3d world so that we can model that. Again, however, we dont know how light, for example, behaves on a 4d object in 4d space. so we can't model that. Not as of now at least. Im dubious of humans ever being able to really understand 4d, all we can see are the shadows and shadows do not interact the same way as real objects.
If only we had four eyes so we could perceive two 3D images at once...
Then we could understand four dimensional objects
Fasteriod, AKA Rowanze We only percive 2D
Your previous statement is definitely correct, each eye can only see in 2d.
2d + 2d = 3d
3d + 3d = 4d?
I'm glad this was recommended to me.

Great video dude!
Tip for the static when screen recording, Use noise suppression! I was having really bad static in my recordings until I boosted the noise suppression. You can do this through the control panel or in your recording program(or both if you wanna swing both ways😉). Hope this helps!
Watching this video actually gave me a huge realization about how easy it is for people to feel out a 3D world on 2D surfaces.
Like, we watch videos all the time. We see the videos as 3D, even though our screens are invariably 2D.
Is also made me understand why you're so excited about VR as a medium.
Dusk Runner If it's so easy for 2D people to feel out 3D, why can't we visualize 4D? you aren't thinking this through, are you?
Cervix Crusader maybe is not why, maybe is when.
@@lkmlmlioj This is a year old comment, but, the 2d people do not see the depth in the video. They see it as we see it, up down left right, no forward or back. which, if you put yourself and imagine that, THEN you can understand how 4d is coming into 3d from ALL directions not just the flat surface, and the 4d cube is different possibilities for the cube, in regards to time. And as it looks is a lot of jumbled information that takes a lot of processing bc we usually only process one instance of this spacetime, and therefore make it a reality because it is dependent on our observation. We are more than we think, we exist in the fourth dimension but cannot see ALL of it. Because this experience is 3 dimensional, like our bodies. THAT is the idea of the spirit and everyone thinks its some big guy in the sky.
@@naruto12445 'We are more than we think, we exist in the fourth dimension but cannot see ALL of it. Because this experience is 3 dimensional, like our bodies.

Exactly! Now Imagine having a "4D TV" in your mind ;)
Trying to imagine what a 4th dimensional being would see is making my head hurt
If you try to imagine it first you must get 3d vision.You can't.
You might need a third eye for that... since we need two to see three-dimensionally .
or just 4 dimensional eyes that can see things in 3d, which can see all sides of a 3d object
A 3rd eye wont do anything new other then add a third reference point for triangulation which only gives you depth that we already have.
Sort of true.
A 3rd eye if it's like a human eye would accomplish nothing.
But a 3rd 'eye' if these are things that capture an entire 'volume' may be necessary to see 4d space in the same sense that we see 3d space with two eyes.
In other words, it would let you see the 4d equivalent of 'depth'.
However, all three 'eyes' in this case would have to be quite different structurally to how our eyes work.
Finally, I kind of understand this a bit. Thank you for leaving the colored lines in so I could visualize that was happening. Well done.
Oh man! Thanks for putting this video together! Really cool experiments and so much food for thought.
Now throw the 4d hypercube and leave a trail!
Cambesa going to 5d!!
SKO Not how it works but nice thinking.
I mean, if you count time as a dimension on its own, that is technically how it works, seeing as how the two other apps counted time as a dimension.
time is a dimension and I've been able to just imagine this trail that anything can leave without much reference. rotating 4D cube is a bit though to grasp however, I do believe VR can make it more intuitive.
LukeDude759 But it wouldn't be 5D that's why I said that's not how it works. Did you even read my comment?

Understanding the fourth dimension would be a lot easier if people would drop the "Time is the fourth dimension" thing
Justamach yes..it's a common misconception to think that SpaceTime is just added to our 3D Dimensions or directions in other words x not just a line that you can draw on a mathematical chart or graph when plotting spatial Dimensions like height width and depth.. SpaceTime is definitely not to be confused with these mathematcal 4D dimensional ideas or constructs-- if people would just Google this for 10 minutes they would find lots of things written online from scientists who have covered the differences.
+rob M.
"not just a line that you can draw on a mathematical chart or graph when plotting spatial Dimensions like height width and depth.."
I beg to differ.
2d is infinite stacks of 1D lines, 3D is infinite stacks of 2D planes, 4D is infinite stacks of 3D spaces. We travel through the fourth dimension, and experience it as the 3rd dimension. In a "2d world", you would travel through the 3rd dimension and experience it as the 2nd dimension.
Name how do you stack 3d objects outside of 3d space? I can't fathom there being any room left!
People who do not know what they are talking about insist that time is the fourth dimension. It is all completely arbitrary and the assignment of dimensions is dependent on what you are talking about.
While it is true that time is not the 4th spatial dimension.
However if you are graphing acceleration then the two dimension are velocity and time, with velocity itself being displacement and time.
Now if your displacement is being plotted in 3 spatial dimensions then time is the 4th dimension.
The 2nd and per se and 3rd examples shown in the video have time as a 4th dimension.
Now I believe that in rocket science they often work in 4D, 3D varying over time, and that it is much rarer for people to work in 4 spatial dimensions, so for now time is the more common 4th dimension.
But yes if you are talking about 5D or even 11D then time is not one of the dimensions
Amazing description of a Hypercube. You even related it to your earlier drawings of a 3d cube on paper (@ 6:23).
I have yet to see anyone explain it in depth like this.
Also, Isn't it amazing that we are creating a sort of 4th dimension with data. Spacial computing is amazing.
Excellent ! Thank you very much. I spent several days to understand 4D space, but the example with the hypercube definitly helped me to understand 4D.
This is the best explanation I've seen for hypercubes. Thank you.
I've often thought about how interesting it would be to make a 4D rendering engine that outputs 3D information. Just like 3D render engines use a mesh of points defined by 3 numbers (x,y,z) and outputs a 2D grid of pixels based on the location and rotation of a camera in 3D space, what if a 4D rendering engine could take a bunch of geometry defined by 4 numbers (x,y,z,t) and output a 3D grid of voxels based on a camera in 4D space? You could take a snapshot, and then look at it in VR (because you'd lose a lot of data if you projected it a second time onto a regular 2D display). I would imagine you'd get some interesting results.
I also thought same thing but now I think about it, the 3D in VR is also projection onto 2D plane(screen) but a bit more interactive one which makes it possible to change the information on 2D screen in real-time to create illusion of 3D. So I think we can't even create a projection of 4D in 3D unless we have a real 3D "screen".
PS, *I think* we can't imagine true 4D untill we step into it.. if it exists anyway, so this 4D concept is false *imo* ;)
PS, PS, cool application btw :D
It's too bad we can't manipulate three dimensional objects in real-time yet
Zulubo Productions Graphics hardware literally just does matrix multiplication, so you can easily write software to simulate whatever dimensional space projected to a lower dimensional space. It's just really cumbersome to do stuff in 4 dimensions, not just because it's one more than three but because 3D objects in R4 can have a lot of really messy geometrical properties that you don't have to worry about in 3D.
Google 4d toys
it has 3d to 2d and 4d to 3d
The moment you showed the hyper-cube, my brain started to feel strange, desperately trying to cope with what I was seeing :-D Really need to see this in the Vive, might make more sense then.
I was thinking the same. Lol. This guy is a genius.
Yeah, I only noticed when editing down the footage how weird it looks back on a screen. It feels totally different and makes marginally more sense when you see it next to your body.
RIght on. Might give it a look today!
Yeah, in VR it's a 3d shadow of a 4d object, rather than a 2d shadow of a 3d shadow of a 4d object. :)
My brain cannot even grasp the possible reality of this. I might watch this a view times.
I did just watch an undisclosed ad, didn’t I?
This helps me understand the concept more easily. Thanks for the explanation
why do I feel like I wasn't supposed to see this
This information is not a secret :-)
There is a 4D puzzle map for Minecraft. Also there is a 4D game in development: ua-cam.com/video/vZp0ETdD37E/v-deo.html
what we were seeing was the "shadow" of a hypercube into the 3rd dimension. exactly how a cube has a shadow projected into a 2d surface. if you were IN the 4th dimension playing around with a hypercube, it would look much much different.
Right! all of the angles and sides would be of equal length; something us measly 3-dimensional beings cannot comprehend fully
Except a 3d shadow can't be cast into a 2d space, at least not in any meaningful way.
The 3d shadow would be on the "floor" of the 2d world, except there is no floor, the dimension of height doesn't exist, and the 2 dimensional creatures only see a 1d line of what's infront of them.
However 2d creature could gain some sort of understanding of the 3rd dimension by studying the cross sections of 3d objects as they pass through the 2d plane.
To 2d being, a sphere passing vertically through their plane would look like a line (if they have 2d depth perception and can identify shapes by the their shading they'll probably recognize it as a circle) that starts off infinitesimally small then grows then shrinks again and disappears.
I think pretty much the only real way to try to intuitively understand 4d shapes is to think about their 3 dimensional cross sections as they move through 3d space.
Thatlas Caulwire i unders5and, but i still cannot think of a 4d
What if we're the shadow of 4d dimension in 3d world that pushed down from 4D dimension until it ends
Really cool - love the way you expand this thought approach for "four dimensional thinking" into tangible demos. Certainly made me think :)
This is awesome! I have attempted to wrap my head around the 4th dimension and it's awesome to be able to visualize what it might be like
This gives one a better understanding of Ezekiel's vision of a "Wheel within a wheel" where it interconnects as he said "without the one destroying the other."
We actually have a type of this thing going on in the Third Dimension: Fractals.
Robbi Huffine True never made that connection, thanks.
Can't a wheel within a wheel also be a rim inside a tire? You could describe that as a wheel within a wheel, if you hadn't seen that before.
A cool thing to think about is a 2d creature and how it sees the world around them, they wouldn't see in 2d, only in 1d, they don't have the freedom of jumping out into the 3rd dimension and looking down onto and even inside of objects in their dimension. Us, 3d creatutes, see in 2d, for example, if time stopped flowing and I could no longer move around objects and was left with what was in front of me it would be like a flat painting, a 2d image. Surely this means that 4d creatures see in 3d. If time stopped flowing in the 4th dimension those beings while sat still unable to fully explore their 4d world would be left with, not a flat image, but a room. Also, you know how while looking at a square on a 2d plane you see it in it's entirety while someone in the 2nd dimension would only see the outter edges of the shape? Does this mean 4d beings would be able to see a 3d object as a whole, all faces as well as the inside and outside, without having to rotate the object or move around it?
TheNBKiller fuckin yes
just yes
love this train of thought, and im going on it right now
TheNBKiller starting to make me think we are the 4th dimensional beings.......
a 1d being sees only a dot. no matter what is before it, a dot is the only possibilty
a 2d being sees a line. no matter what is before it, a line in varying lengths is the only possibilty
but do 3d beings see only shapes, any number of shapes, but only shapes
this is the tricky part, are we 3d, seeing shapes, but percieving their 3rd dimension
or are we 4 dimensional actually bearing witness to 3 dimensional objects but incapable of witnessing ourselves(much like a square percieves itself as a line)
what if somehow someway, the 4th dimension is simply perception
what if the 5th is emotion, and so on so forth (if this concept holds true I can see time being the 4th, or 5th along with perception whereas I typically disapprove of the time being a dimension concept)
I usually prefer to keep talks about 4d in solid form but in reality the concept of 4d objects makes no logical sense to us. like trying to tell the square to go left or right......square is gonna look at you and go.....we are both lines bro....all we do is long or short(point being square struggles to even understand up and down despite having that axis)
i guess what im getting at is while I do believe the jump from 1d-2d and 2d-3d creates exponential growth, my question is, did it create so much growth that we are that far above squares thinking and we can ask all of these questions, or are we another level above 3d and that explains our vastly increased ability to ponder these questions
woah dude
The only reason we perceive three dimensions is because we have two 2D shapes to work with. That's why closing one eye eliminates depth perception. Now if you had two 3D OBJECTS to mesh together in the brain, then you'd be looking at the fourth dimension.
Theoretically this means if you had four eyes... you would be capable of seeing the fourth dimension.
2D x 2 = 3D, 3D x 2 =4D, so 2D x 4 = 4D
TheNBKiller brother your comment made me understand much more of this
This was really very informative! Thank you for making the video!
8:40 nice breakdown. the hypercube is a cube in time.
The 2 opposing cubes that are not connected shown here are symbolic, portraying 2 end states apparently in opposition but which are just extreme polarities of movement.
That's why the shape looks like this in 2d space. A moving figure needed to be portrayed so the 2 end states are shown,
Like a cube being 2 perpendicularly connected squares, so too is a hypercube 2 perpendicularly connected cubes.
It only looks like this on paper, in actuality every 4d object resembling the shape of a donut since the movement is from inside out for each living body.
Not like turning your insides out, but from within each cell, like how a plant grows and such

I had just come back from watching A Wrinkle In Time in the movie theater (which was quite disappointing, I read the book first) and we were eating at Cheesecake Factory while having a good discussion about four dimensions. It’s just so hard to grasp and to think about. I think that’s what makes it interesting. I heard a good line from someone I can’t remember. They said “If we can conceive it, it isn’t new. It’s just a mashup of several other things.” The way we view a tesseract, or a hypercube, or whatever you want to call it, is as a mashup of several cubes. But when we look at a drawing of a box, it’s not a mashup of several squares. It’s a cube. I think if we try and look at the shape as the shape it is, we could get a better understanding. But that’s probably impossible. Humans can not think of what we haven’t seen.
This is the best I've ever been able to understand the 4th dimension- thank you!
I'm still not fully understanding 4d, But, this helps out a ton and I feel I understood a bit more. like I'm closer to understanding it. so thank you. :)
ZennSkye man no one can fully understand it hahahaha but we can try it, and that is the best part of matematic and fisics, is so much knowledge than we can keep hahahahaha
Canalbiruta, fisics?😂😂😂😂😂
You mean Physics...
That Hasan yeah of course lmao
Thanks for the video, I found it very interesting. I have never played with VR before.. which headset do you recommend and which can use the programs you describe in the video? Thanks so much for doing this demo. I enjoyed it.
This is incredible!
Watching this made my day!
first off, great video! question: now that we know what a cube looks like in 4D, what do other shapes look like? how about a tetrahedron, a sphere...a cat? id love to see more!
A being of any dimension can only truly perceive it's own world in a dimension that is one less of it's own. For example, us 3d beings see 2d flat objects but our brains have learnt to use 2 eyes to interpret the 2d images from 2 perspectives as a 3d object. Close one eye and the world is flat. By closing one eye, the only reason we know whether an object is coming toward or moving away from us is because the size of the object changes and our brains have learnt that generally objects (or images) getting bigger means it's getting closer and vice versa.
We cannot perceive any dimension other than 2d. A line always has a tiny bit of breadth when we draw it. So it's 2d.
The case is even worse for a point dimension as our representations all have length and breadth and don't even get me started on the 4th dimension.
Taking this analogy, it would be impossible for a 4d being to conceptualize a 1d shape and would have a false 2d representation as everything would be 3d for it.
And for a 2d being, it would have a false zero D concept(point) and it would be impossible for it to perceive "-1d".
All this is of course taking into account that no dimensional being can perceive reality as a being of 1 dimension higher than itself.
In short, we see 2d shapes.
2d beings see lines.
1d beings see points.
4d beings see 3d shapes.
5d beings see 4d shapes. Etc etc...
you know any beings of other dimensions?
People always forget that we have another piece of information for depth: focus
An item further away will be out of focus when you're looking at a closer item.
@@joeywargo3650 You are correct when speaking of seeing with only one eye. My right eye has been very weak from birth. When driving a car, I have to estimate objects based upon what is kinda, sorta, a 2 dimensional pallet. When a basketball is tossed toward me, since there is no background by which to judge distance, all I see is a circle getting larger and larger. No one ever chose me to be on their team! LOL
You can still focus and unfocus objects with one eye
A 3 dimensional point is an electron
2:42 Perspective vs Orthographic! Thank you so much for explaining that to me. I learned both, but I've never figured out how to use them. Now that I understand them better, I think I've figured it out! WOOT! 🎨👨🎨
Ah, so this is what happens when you loose something... A 4D being just takes then into the 4th dimention
There is no hyper , hyper dimension. all are trapped like small box , big box, bigger box , large box and larger box. If you are not outside of this big box , you can not see this box. Every dimension have it own three dimensions
@@shweyee763 what are you trying to say?
this is so awesome fuuuu i would've never leave that cube room if i had a vive
Smoke some dmt, best 4d visualizer out there
Exactly what I was thinking man. Seeing that hypercube made me think of my breakthrough experience
@Kojiro Vance so i see you're watching too much psychedlic hollywood propaganda
@@gt42636 hell yea man, the image of the evershifting shape i was portrayed reminded me of a 4th dimensional object. It made me question alot of stuff about the world i came back to. Seemed more real than our current reality imo
@@Anon_2025 I showed this to my bro and asked him if it reminded him of anything and he also made the connection to dmt. His experience was full of "cubes" and he said there was a "cube king" entity that was right up in his face and made out of constantly changing cubes and shit
It is better injected or drink Ayahuasca tea...which has DMT...
This is awesome man, I think I could have hours of fun making chair flight path sculptures in that last software
Thanks for this video. Makes a lot of sense and once I get a VR headset (this is the first reason to justify I’ve found) then will come back for the link, thanks!
Out of interest, is there a way to give each cube a colour to keep track of them as it spins?
You’re playing with a 4D object but you’re only able to see its shadow.
You speak in my language my friend, when you said at the beginning that "you sounded like what you were saying was crazy" and I remember thinking that this was so hard to explain, and that it was impossible to explain. Now, after researching and daydreaming, DRAWING THINGS OUT, -relearning- a lot of math, and had fun...this makes more sense than life itself, and 'normal' life that most see is foreign to me :) I have always loved sacred geometry and saw the bigger picture that many have a hard time understanding. It just seems to click after some time. Even my girlfriend who hated math when we met, now teaches me things...the student has become the teacher...something that should happen much more in school, and is the future to come!...ready or not, its nothing hard. It is just a new point of view - always been there - just behind the scenes... Thank you for sharing and keep up the good work and have fun!!! RIP TESLA ~Ryan Merrill
Just follow you heart, and follow the numbers, and find and follow the patterns, the infinity of infinite infinities. haha
Okay Einstein, we get it.
This was SO damn interesting and it was uploaded 2 years ago. I wonder what new insights have been gained since then!
Thanks for sharing this! I’ve always wanted to better understand 4th dimensional space too
I was always under the impression that the 4th dimension is time
This makes me feel funny in my tummy.
7:53 No one told me there would be rhombic dodecahedrons =D
I prefer the plural term "dodecahedra" : )
You should checkout the origami way to build em. You can also order dice in this shape! Yeah, I've been sorta obsessed w/ this shape since making this video.
Thanks for your thoughts
Hi! Great context, thanks for sharing, your explanation about the hypercube is very clear and informative. Is that possible for you to turn on the caption adding? I’d really like to show this to some friends
11:27 so this is the power of gold experience requiem
Wha- wha- wha- wha- wha-
4:06 it's isometric not isomorphic. But awesome video! I've been waiting to hear of something like this for vr!
Tip of the hat to you sir.. out of all the scientists and so called smarties that I've tried to understand 4 dimensions from.. you have come the closest to giving me a truly understandable vision.
Thank you so very much Albert!
Is it safe to say, all dimensions above the 3rd is optical illusions? And/or self-reflective of their shapes? (I suppose 3d to a 2d world is also optical illusion)
Time is not optical as such. 3d life is 4d life because time is the 4th dimension of space-time. So I don’t get all this talk about this mysterious 4th dimension
What if we are a shadow of the 4th dimension
We are

you see four d all the time, corner of eye, quick things your mind dismisses as nothing, it intersects our three d, because it surrounds and occupies it at the same time
Really cool! Great explanation!
really, very great, and effectice explanation *greets from one tech/science guy to another*
The video was uploaded in 2016, People here are from 1 to 5 hours ago
youtube recommended page...what a strange thing it is
4 dimensional time brought me here
does it have any relation to the real 3d world? i mean everything in real life could be imagine as 4 or 73 dimension object, but still there is no orthogonal dimensions more than 3.
Wow I loved the vid. I would like to talk to you about the 4d and up. I felt you were closer to explaining it in the 2nd vr with the figure 8.
Awesome video Albert. Closest representation of 4D in 3D. Thanks.
My question now: If we can at least think of the 4th dimension, can objects in the 2nd dimension still move upwards? And sure I know that's not how it works but we just heard about 4th dimension so why not?🤔
They can if they are a cross section of 3D objects
Please set manual focus. It is so painful to watch the video when it gets blurry all the time :( But the rest of the video is really interesting! Thank you!
Very much appreciate the direct constructive criticism. I'll take a look into it with my camera.
I loved your explanantion , thank you soo ssoo much , nd that app is great too...
DUDE
do you still have that program for making frames of a motion??? that would be an epic effect to have in music videos or something!!
Dude I totally love the way of your perception and thinking!
When you fear death, remember that you are merely ascending to a higher dimension. Like a dot, a line, a square, a cube and a hypercube...what you were isn't lost. It just becomes...more.
And so, after death, you can't become anything else than a hyperhuman
What the shit
How do you know that though
Ashes to ashes, dust to dust, you ain’t coming back. You dead.
You could make a religion out of this
This was great. Enjoyed !!!! ❤
would be interesting to see the visual outcome of attenuating frequencies, harmonics, impartials, pre delay, reflections, wave characteristics and all music/sound related data to a VR environment that allows variable conditions to affect\test the source sounds to be observed and or interacted with in relation to the geometry and math of all these dimensional and primarily visual concepts. Also as soon as you waved the tracers, i thought of moment to moment, time segments we live in and how much data each holds, to give us the "perception" of time, by the differences we observe in each tracer from one to the next, allowing us to see patterns and predict, wait then move forward, remember the past, etc. How that ties in visually with the human perception of all this together in one vr app...lol
cheers
